AB  - A major component of minimally invasive cochlear implantation is atraumatic scala 
      tympani (ST) placement of the electrode array. This work reports on a 
      semiautomatic planning paradigm that uses anatomical landmarks and cochlear 
      surface models for cochleostomy target and insertion trajectory computation. The 
      method was validated in a human whole head cadaver model (n = 10 ears). 
      Cochleostomy targets were generated from an automated script and used for 
      consecutive planning of a direct cochlear access (DCA) drill trajectory from the 
      mastoid surface to the inner ear. An image-guided robotic system was used to 
      perform both, DCA and cochleostomy drilling. Nine of 10 implanted specimens 
      showed complete ST placement. One case of scala vestibuli insertion occurred due 
      to a registration/drilling error of 0.79 mm. The presented approach indicates 
      that a safe cochleostomy target and insertion trajectory can be planned using 
      conventional clinical imaging modalities, which lack sufficient resolution to 
      identify the basilar membrane.
